BACKGROUND OF THE INVENTION

1. Fields of the invention

The present invention relates to a cooling fan, and more particularly,to a cooling fan with an atomizing device for generating atomized waterparticles to cool the temperature.

2. Descriptions of Related Art

The conventional fan generally comprises a motor with a shaft whichdrives multiple blades to rotate so as to generate air flows toventilate and remove heat away. However, when the temperature is high,the air flows generated by the rotation of the fan blades cannot reducethe high temperature and the cooling feature is limited.

The present invention intends to provide a cooling fan which is able toquickly reduce the temperature.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 and 2, the cooling fan of the present inventioncomprises a body 1, an atomizing device 2 and a water connection plate3.

The body 1 comprises a housing 11 and multiple blades 12 are located inthe housing 11. A motor 13 is connected to the housing 11 and has ashaft 131 which is connected with the multiple blades 12. A pole 14 isconnected between the housing 11 and a base 15.

The atomizing device 2 is connected to the body 1 and comprises anoscillator 21 which is connected to the pole 14. A blowing device 22 islocated beside the oscillator 21. A mask 23 is connected to the pole 14and located in opposite to the oscillator 21. The mask 23 has an outlet231 to which an end of a connection pipe 24 is connected. The other endof the connection pipe 24 is connected to the first end of a guide pipe25. The second end of the guide pipe 25 is located in the pole 14 andextends along the pole 14, the second end of the guide pipe 25 thenextends to a connection portion of the pole 14 and the housing 11. Anozzle 141 is connected to the second end of the guide pipe 25 andlocated behind the housing 11. A water tank 26 is connected to the pole14 of the body 1 and has a valve 261 which is located corresponding tothe oscillator 21. The water tank 26 has a transparent window 262 so asto observe the water level in the water tank 26.

A water collection plate 3 is located at the underside the housing 11and beneath the blades 12 of the body 1. The water collection plate 3has hooks 31 which hook the body 1 so that the water collection plate 3can be taken out and cleaned.

Further referring to FIG. 3, when using the cooling fan, the motor 13rotates the blades 12 to generate air flows which move toward the samedirection.

Referring to FIGS. 4 to 6, the atomizing device 2 is activated while theblades 12 rotate and the oscillator 21 makes the water particles fromthe valve 261 of the water tank 26 into atomized water particles ormist, and the blowing device 22 delivers the atomized water particlestoward the mask 23 which collects the atomized water particles and theatomized water particles are sent out from the outlet 231 of the mask 23and move along the guide pipe 25 via the connection pipe 24. Theatomized water particles are then guided by the guide pipe 25 andejected from the nozzle 141.

The atomized water particles ejected from the nozzle 141 is delivered bythe air flows generated by the blades 12 so that the atomized waterparticles cools the high temperature and the users feel comfortablewithin short period of time.

Some of the atomized water particles are delivered via the air flowsgenerated by the blades 12 and some of atomized water particles areattached on the blades 12. The atomized water particles attached on theblades 12 are condensed and drop down into the water connection plate 3located at the underside of the housing 11. Therefore, the water iscollected and is avoided from dropping to the floor to cause more dustand dirt. When the water collected in the water collection plate 3 isfull, the users can unhook the hooks 31 of the water collection plate 3from the housing 11 and remove the water collection plate 3 and cleanit. The water collection plate 3 is then installed to the housing 11 bythe hooks 31. The users can observe the water level in the water tank 26via the transparent window 262 so as to add water into the water tank 26when needed.

The present invention provides the following advantages:

-   -   1. The atomized water particles ejected from the nozzle 141 is        delivered by the air flows generated by the blades 12 so that        the users feel comfortable within short period of time.    -   2. The oscillator 21 is located beside the blowing device 22 so        that the atomized water particles made by the oscillator 21 can        be sent toward the desired direction to increase the cooling        efficiency.    -   3. The water connection plate 3 is located at the underside of        the housing 11 so as to collect the water attached to the blades        12 such that the water is avoided from dropping to the floor to        cause more dust and dirt.    -   4. When the water collected in the water collection plate 3 is        full, the users can unhook the hooks 31 of the water collection        plate 3 from the housing 11 and remove the water collection        plate 3 and clean it. The water collection plate 3 is then        installed to the housing 11 by the hooks 31.    -   5. The users can observe the water level in the water tank 26        via the transparent window 262 so as to add water into the water        tank 26 when needed.

While we have shown and described the embodiment in accordance with thepresent invention, it should be clear to those skilled in the art thatfurther embodiments may be made without departing from the scope of thepresent invention.
